Subtracting Negative Numbers Using Integer Chips

This video tutorial teaches how to subtract integers using integer chips. It begins with an introduction to integer subtraction and explains how integers can be modeled with yellow and red chips, representing positive and negative numbers, respectively. The concept of zero pairs is introduced, where opposite quantities cancel each other out. The video then reviews the rules for adding integers with like and different signs, emphasizing the importance of zero pairs. Several examples are provided to illustrate integer subtraction, including scenarios involving debt and spending. Advanced problems are also covered, demonstrating the use of zero pairs to solve complex subtraction problems.

What do yellow chips represent in the integer chip model?

• Zero pairs

• Negative numbers

• Positive numbers

• Fractions

What happens when you add numbers with different signs?

• You create zero pairs

• You add them directly

• You subtract them

• You multiply them

If you start with a value of positive 1 and add a zero pair, what is the new value?

• Negative 1

• Positive 1

• Zero

• Positive 2

In the example where you have $3 and spend $5, what is the final value?

• Negative 2

• Positive 5

• Positive 2

• Zero

What is the result of 3 minus negative 3 using integer chips?

• Positive 3

• Positive 6

• Zero

• Negative 6
